Theoretical Analysis of Low-Capillary Number Dip-Coating Processes

open access: yes, 2007
本文旨在以理論分析探討浸泡塗層的流場分佈與塗層厚度、液膜長度的關係。藉由適當的因次分析,可定義出三個不同的流場形式分別為:低毛細數流場、中毛細數流場、高毛細數流場。而每單一個流場又可依不同的特徵區分成三個區域,分別為:區域一,固定厚度區;區域二,類一維流域動態區;區域三,靜態區。區域二及區域三將分別透過雙精度五階的數值方法(Runge-Kutta- Fehlberg Method)求得其解,並將其解平滑的接在一起以便得到整個流場的邊界形狀。經由計算的結果可以得知 ...

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

open access: yesAdvanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Ultrathin Quasi‐2D Perovskite‐Organic Segregated‐Structure Coupling for High‐Performance Narrowband Photomultiplication Detectors

open access: yesAdvanced Science, EarlyView.
Quasi‐2D perovskite‐organic segregated‐structure coupling enables low‐power narrowband photomultiplication photodetectors with 110 nm perovskite layer. The optimal device achieves 1200% EQE and 1.82 × 1011 Jones D* at 3 V, offering a new strategy for miniaturized high‐selectivity optoelectronic sensing.

Chiral‐Encoded Pt‐Ir Surfaces as Apparent Spin Filter for Enhanced Oxygen Reduction

open access: yesAdvanced Science, EarlyView.
The Chiral‐Induced Spin Selectivity (CISS) effect is employed in chiral‐encoded mesoporous Platinum‐Iridium (Pt‐Ir) electrocatalysts to enhance the oxygen reduction reaction (ORR). A break in spin symmetry leads to a substantial antagonistic difference in activity (>200%) when comparing two enantiomorphs of the same electrode.

Dynamic Self‐Clickable Decellularized Matrix Hydrogels for Regulating Vascularity and Enhancing Muscle Regeneration

open access: yesAdvanced Science, EarlyView.
Dynamic decellularized hydrogels are prepared using bovine decellularized small intestine submucosa (SIS) norbornene (dSIS‐NB). Bovine dSIS contained significant amounts of disulfide‐rich fibrillin‐I, enabling ‘self‐clickable’ thiol‐norbornene gelation and spatiotemporal tuning of hydrogel physicochemical properties.
